You know, adding a CPU VTT Voltage adjustment would do wonders for overclockers.

Thanks for the information on who to contact Mike.

Some preliminary observations

Using OCGenie rebooted severaltimes them rebooted into a dead screen and had to clear CMOS

Manual overclocking.  Got up to 210 BCLK with memory and QPI set at low ratios but when trying for higher ratios like 200BCLK, 1600 for memory and 5800 QPI I could boot inot windows but LINX caused a freeze up

Got the board about a week ago so I'm still playing with it.
